Struct PerColor 

pub struct PerColor<T>(/* private fields */);

A pair of values, one per Color.

Use this anywhere two per-colour values would otherwise become two named fields: it makes for color in Color::ALL work, and it makes forgetting one side impossible.

Implementations

impl<T> PerColor<T>

pub fn new(black: T, white: T) -> Self

Builds a pair from its black and white halves.

pub fn black(&self) -> &T

The black half.

pub fn white(&self) -> &T

The white half.

pub fn get(&self, color: Color) -> &T

The half belonging to color.

pub fn get_mut(&mut self, color: Color) -> &mut T

Mutable access to the half belonging to color.

pub fn into_parts(self) -> (T, T)

Consumes the pair, yielding (black, white).
